This is the first clearly different but unidentifiable taxon to be split from the peruvian sample. The deep gena and plumose arista suggest that it might be a dexiine and further to this it has a very elongate proboscis and strong median facial ridge – bearing a string similarity to the palearctic genus Prosena. However, Prosena does not exist in the neotropics so this has perhaps evolved seperately but with similar morphology.
EDIT (Monty Wood, 26/9/2010): This genus was unknown to Monty but it is closest to Prosenoides.
